Abstract: 1442544 Character generator ROCKWELL INTERNATIONAL CORP 16 April 1974 [11 May 1973 (2)] 16530/74 Heading G4A A character generator, by executing a program of instructions individual to a character to be displayed, establishes, for each successive value of one co-ordinate in a two co-ordinate system, values of the other co-ordinate representing the initial and terminal points of a section of the character along the particular value of the one co-ordinate. The generator may be used in conjunction with a CRT whose beam is alternately unblanked and blanked at successive ones of generated Y coordinate values during its Y scan at each successive X co-ordinate value, the Y values being computed during the preceding scan. The program defines the character in its maximum size, scaling factors being used to display smaller sizes. An exemplary program is shown in Fig. 3B to develop the character of Figs. 3A and 3C. The instructions are taken in sequence, each instruction being started at a cycle determined by a value in the preceding instruction and all instructions being executed in each successive cycle until cancelled (EOLP) or replaced by a later instruction. The allowable instructions include BOLP instructions which establish initial Y values for a pair of outlines, e.g. 1 and 2, Fig. 3C, defining the initial and terminal point of a section of the character. The Y values are stored in increasing value in a circulating store together with an identification of which outline they relate to and are compared with the current Y value of the beam position to control unblanking and blanking of the beam. Slope instructions CM establish a slope for a specified outline by specifying a Y increment (or decrement) which is used to modifiy the current Y value for the next scan, the increments (and decrements) being read from an R.O.M. by coded signals M in the instruction. Change slope instructions CK progressively modify the slope as the current X value increases, each slope being maintained for a number of cycles (X values) determined by values read from an R.O.M. so as to match the outlines traced to a curve more closely. EOLP instructions delete the Y values for specified pairs of outlines and an EC instruction deletes all Y values, terminating the display. The Specification describes the system in some detail, specifying the R.O.M. contents and the way in which they are arranged and used so as to reduce the amount of storage required.

Abstract: A DC arc furnace has a hearth formed with an extension in which a melt-contact electrode is positioned, and has an arcing electrode laterally spaced from this contact electrode. This results in the formation of an arc that is oblique in a direction facing away from the contact electrode. To prevent the arc from being excessively destructive with respect to the furnace vessel's side wall toward which the arc was directed, furnace charging material, in particulate form, is continuously fed to a melt in the furnace, as a flow directed into the arc foot spot formed by the oblique arc, resulting in a maximum efficiency of energy absorption of the normally cold charging material and at the same time, via the charged material, shading the lining of the furnace vessel from an attack by the arc.

Abstract: A method for establishing and reading secret information using holographic interference pattern techniques. A holographic plate is placed in a holder and exposed with a laser light reflected from an object and a reference laser light to create a hologram. The exposed hologram is removed and a second holographic plate is inserted into the holder. The object, which may be a matrix, is selectively deformed to provide letters or numbers in accordance with the secret information to be established. The second holographic plate is then exposed with a light reflected from the deformed object and with the reference laser light to create a second hologram. The information contained on each hologram, when viewed individually, appears to be substantially identical. However, when the two holograms are later combined and illuminated, the secret information in the form of a holographic interference pattern will be observed in the hologram.

Abstract: According to the invention, a simple measuring arrangement 10 is produced, designed to determine whether a so-called spring strut 50 which is part of a vehicle's front wheel suspension has become deformed, specifically, crooked, and the arrangement is intended to be used primarily on wheels with disk brakes. The arrangement is used in place, that is, on a spring strut 50 mounted in place on the vehicle, and it is only necessary to remove the wheel with its cover and rim in order to expose the disk brake 40. The measuring arrangement consists of an upright 12, which is joined to a base part 14, 20 arranged to be fastened, preferably by permanent magnets 24, 26, to the outside of the brake disk 40. The upright 12 carries a moveable measuring arm 30 provided with a length scale, which projects out from the upright 12 perpendicular to the plane of the brake disk 40 and which in turn carries a moveable pointer arrangement 36, which can find the centre 60 of the upper fastening 55 of the spring strut 50 to the chassis. Once adjusted, the perpendicular distance a from said fastening centre 60 to the plane of the brake disk 40 can be read off from the scale of the measuring arms 30. Knowing this distance, one can determine whether or not the spring strut 50 is deformed (crooked). <IMAGE>

Abstract: An improved method and circuit is provided for processing waveforms from a railway car heat signal to eliminate spurious signals and to differentiate between roller bearings and friction bearings in a railroad hot box detector system. The waveforms generated by passing bearings are discretely sampled and spurious signals are eliminated by considering only those signals that fall within the crossing points of a threshold value. Discrimination between roller bearings and friction bearings is obtained by determining the ratio of the sum of the discrete values of the amplitude of the waveform within a first set of samples between the crossing points to the sum of the discrete values of the amplitude of the waveform within a second set of samples between the crossing points.
